[FIXED] jQuery AJAX parses HTML response as JSON

Issue

I cant find anything on the web about this mysterious bug. I wrote a simple Ajax calling a CakePHP Controller-Function to render a simple View. Finally i want to put that rendered HTML into a Popup:

The Ajax:

$.ajax({
    url: $('base').attr('href') + '/myController/renderPopupContent/' + this.view,
    type: "GET",
    dataType: "html",
    context: this,
    success: function( data ) {
        this.content = data;
        this.show();
    },
    error: function(xhr, status) {
        showMessage(status, xhr);
    }
});

Now i get a jQuery-Error which says:

Uncaught SyntaxError: Unexpected token <

This is because jQuery tries to (automatically^^) parse the response as JSON. If i debug the script it breaks at jQuery (1.9.1) at Line 541 and it really tries to parse that html-response (STRING!) into/from JSON.

How can i avoid this and get jquery known of the dataType "HTML"

Additional Info:

The jQuery-Error (@Ln541) occures after an "alert();" in my success-callback, so the Ajax is already done when the error is thrown.

Solution

Somewhere in another JS-File i found this snippet:

$(document).ajaxSuccess(function(evt, xhr, options) {
    var response = $.parseJSON(xhr['responseText']);

This obviously fires after every ajax and tries parsing the response.
